LeBlanc joined the Mean Green coaching staff prior to the 2016 season as the defensive line coach. The North Texas defense held opponents to 8.7 points per game fewer than the 2015 team. That turnaround in scoring defense was the 13th-best mark in the country.
Before joining North Texas, LeBlanc had coaching stints with Southern Miss, Wyoming, LSU and most recently Pearl River College.
LeBlanc spent two years at Southern Miss, 2013 and 2014 and helped revitalize the defensive line in his time. In his first year LeBlanc managed a defensive line led by Khyri Thornton, who was named second team All-Conference USA and selected in the third round (85th overall pick) to the Green Bay Packers in the 2014 NFL Draft. Under LeBlanc's tutelage, Thornton recorded 39 tackles, including 16 solo tackles and 23 assisted tackles.
In his one season at Wyoming in 2012, he made a lasting impact on the Cowboy program, coaching defensive tackle Mike Purcell to All-Mountain West Conference first team honors. Purcell was third on the team in tackles, a tough mark to achieve for an interior lineman, with 83 while recording eight tackles for loss. Purcell was also one of two Wyoming seniors selected to play in a postseason collegiate all-star game.
LeBlanc went to Wyoming from LSU, where he was an assistant strength and conditioning coordinator from 2008-11. Prior to working in the LSU athletics department, LeBlanc was the defensive line coach at Missouri State for two seasons in 2006-07.
